Maybe. All the machines I've seen it on are current-software:
$ uname -a
Darwin minim4.sss.pgh.pa.us 24.5.0 Darwin Kernel Version 24.5.0: Tue Apr 22 19:53:27 PDT 2025; root:xnu-11417.121.6~2/RELEASE_ARM64_T6041 arm64
$ cc -v
Apple clang version 17.0.0 (clang-1700.0.13.3)
Target: arm64-apple-darwin24.5.0
Thread model: posix
InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin
If it's OS-version-specific, that raises the odds IMO that this
is Apple's fault more than ours.
